You can't. However, with 2 Transfer Paks, Pokemon Staduim 2, Yellow, Red, or Blue Version, and an N64 (or more simply 2 games, 2 game boys, and a connection wire) you can trade a Mewtwo (and duplicate it if you want) to Crystal Version.
You can only using a Nintendo mystery gift.
Mew cannot be caught in Pokémon Crystal. Try to trade it from other games.
You cannot catch Mewtwo in Pokemon Crystal, but you can trade it from a Pokemon Red or Blue. Hope this helped :)
You cannot catch Mew in "Pokémon Ruby."or you can get mew-two in fire red or leaf green.
You can't catch Mewtwo on XD, Colosseum, Ruby, Sapphire or Emerald. Mewtwo can be caught in the Fire Red or Leaf Green Version then traded over to Emerald, Ruby, Sapphire, Colosseum or XD.
I don't think you can catch MEW without a action replay. But you can catch MEW2 in Pokemon Fire Red or Leaf Green. You CAN'T cach mew without an action replay, but you can trade mew-two from the other games to the newer ones
No, Mewtwo cannot be caught in Pokemon Crystal. It can, however, be traded from Pokemon Red, Blue, or Yellow.
